[Nouveau] [PATCH AUTOSEL 5.18 62/93] drm/nouveau/nvkm: use list_add_tail() when building object tree
From: Ben Skeggs <bskeggs at redhat.com> [ Upstream commit 61c1f340bc809a1ca1e3c8794207a91cde1a7c78 ] Fixes resume from hibernate failing on (at least) TU102, where cursor channel init failed due to being performed before the core channel. Not solid idea why suspend-to-ram worked, but, presumably HW being in an entirely clean state has something to do with it.
